Title: Nonionically stabilized polyester urethane resins for water-borne coating compositions
Inventor: BALATAN SERGIO E
IPC: C08G18/12
Filed: 1990-07-17
Granted: 2000-11-07
Abstract: Laterally stabilized, water-miscible polyester polyurethane resins, useful as principal binder resins and as pigment grind resins in water-borne coating systems are the reaction product of one or more polyols, one or more polyisocyanates, and a polyester prepolymer formed by the reaction of a polyether alcohol, one or more polyols, and one or more polyfunctional carboxylic acids. The resins have a polyester polyurethane backbone with pendant polyether groups, attached to the polyester segments of the backbone, which serves to solubilize arid stabilize the resins in aqueous media. The resins have small dispersion particle size at the same or higher molecular weights than similar prior art resins, and produce better metal flake orientation when used as the principal resins in base coat formulations which contain aluminum and mica particulates for "metallic" effect coating finishes.

Title: Improvements in safety barriers for roads
Inventor: GARCIA BALLESTEROS ANGEL
IPC: E01F13/00
Filed: 1991-09-04
Granted: 1999-03-30
Abstract: The aim of the invention is to supply a safety barrier which acts as a dividing and/or protecting wall between lanes of opposite directions in roads.  The barrier consists of a series of light weight modules, filled of a conventional material as ballast to give them stability and resistance.  The modules are noticeably rectangular prismatic bodies with top apertures which act as loading nozzles for the filling material, and with lower transversal canals for the circulation of water.  One type of module is male and the other female, and to form the barrier they are placed alternatively the ones on the others on the wearing course of the road.  The modules can be dismantled to leave an open way in the barrier; they can be articulated or even rigid between themselves and anchored to the ground.

Title: Filling containers
Inventor: TOWNSLEY ROBERT CHARLES
IPC: G01G15/00
Filed: 1990-06-11
Granted: 1996-02-20
Abstract: A succession of containers passing along a filling line are weighted empty at a tare station (4), filled at a filling station (6) and weighted full at a gross station (7). The tare and gross weight for each container are input to processing means (20) which controls the filling station (6), by establishing a set point for the filling means (20). The processing means calculates for each con-tainer the net weight or volume of its contents and averages the contents of a batch of containers. Should the average contents fall outside a predetermined tolerance of a target weight, the processing means applies a correction factor to the set point of the filling means to obtain a new-set point for a subsequent batch of containers.
